ANTISKIDDING AND TRACTION DEVICE FOR AUTOMOBILE-WHEELS.

Application filed February 17, 1910. Serial No. 544,416.

To all whom 'it may concern:

Be it known that I, WILLIAM REAGAN, citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAntiskidding and Traction Devices for Automobile-Wheels; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to anti-skidding and traction devices for wheelsof vehicles, particularly automobile wheels, and is a species of thetype of similar devices shown and described in an application filed bymeFebruary 12, 1910, Serial Number 5%,583.

The invention consists of a plurality of pivoted calk-bearing sectionsarranged in groups, at intervals, around the circumference of the wheel,and'means for holding the groups in their spaced relation, as will behereinafter described, and stated in the claims.

One of the, chief objects of the invention, is to so construct andarrange the calk-bearing sections that the calks of the intermediatesections will be in staggered relation to those lying upon either sidethereof, so that they will have a creeper efiect in their action, whichwill not only check any tend- .ency to skid, but will materially assistin traction.

Other-objects of the invention will become apparent upon a more completedisclosure thereof.

In the drawing: Figure 1 isa' side elevation of a section of anautomobile wheel,

showing my invention applied thereto; Fig. 2, a transverse section ofthe tire, showing a group of the devices arranged thereon; Fig. 3, a topplan view of a group ofvthe calkbearin sections, showing the staggeredrelation of the calks; Fig. 4c, a perspective view of one of thesections,'and Fig. 5, a similar view of the securing-block.

Referring to the several views, the numeral 1 indicates a number ofmetallic calk-bearing sections, arranged in a pluralityof parallel rowsand pivoted directly to each other by removable pins or pintles 2. Eachsection is slightly curved on its under surface, to conform to thelateral curvature of the tire, and provided with a plurality ofsharpened calks 3, the calks of the intermediate row Specification ofLetters Patent.

' of sections being in staggered relation to those lying upon eitherside, as shown in Fig. 3. Pivoted between each of the outer end sectionsof each group of calk-bearing sections, is a securing-blockhaving'oppositely-disposed books 5, to which are attached the retainin-members, preferably chains 6) These hoo s are so disposed that thecalk-bearing sections,--to whichthey are pivoted, prevent thedisengagement of the retaining-members or chains therefrom, but bytheremoval of the pintle, connecting the block to the calk-bearingsections, said members or chains may beremoved from the hooks.

The pivoted calk-bearing sections are arranged, at intervals, 1n groupsaround the circumference of the wheel, the groups being held in theirspaced relation by the retaining-members 6, as shown in 'Fig. 1.

By arranging the. calk-bearing sections in the manner shown anddescribed, the number of calks is. greatly increased, thereby increasingthe holding-action and .materially assisting traction. As stated in theapplication hereinbefore referred to, this increases the disposition ofcertain of the calk-bearing sections at points in the lateral curvedsurface of the tire, which points approximately coincide with the sideof the flattened loadbearing portion thereof. This is of great.advantage, because the calks of those sections, lying upon the sides oftheflattened portion of the tire, enter or penetrate the ground to agreater or less extent, notwithstanding they point at a certain angle ofinclination. The holding-action and traction is also increased byarranging thecalksv in staggered form, as is obvious, and, by reason oftheir peculiar shape readily penetrate or engage the surface of theroad, pavement, or ice and snow.

- Having thus fully described my invention What I claim, is v V 1. Ananti-skidding and-traction 'devlce, having in. combination a lurality ofrows of calksbearing sections pivoted di rectly t o each other, andcalkebearing section retaining members, the calk-bearing sectionsbeingflexibly connected to the retaining members, and .the'calks' of theintervening, row of sections staggered inrelat-ion' tothe'outer rows.
